Stop AppDomain Timeout

Wally96333 61

I am developing a WPF app that executes code in a separate appdomain. I've noticed that the appdomain times out and terminates after 6 minutes. After doing some research, I discovered that the lease on the connection expires after 6 minutes.

*** P_Exception.GetType : System.Runtime.Remoting.RemotingException
*** Message : Object '/27e4129e_033b_46af_8822_38bf75745b2f/og_uk3rcfzteewc9vfcp1qgl_5.rem' has been disconnected or does not exist at the server.

I do not want the appdomain to terminate until the main appdomain does, or until there is a call to the Unload method. I cannot find anything in the documentation on how to shut off the timeout, or set it to infinity.

To be clear: The appdomain comes up and runs as expected without any errors, and everything is running on the local machine: There are no servers involved as everything is running on the local machine.

Any assistance with this would be appreciated.

Maybe the error message does not mean that the AppDomain terminates automatically after 6 min.

From what research that I've done, it seems that it's the connection that times out. Perhaps I need to do something with MarshalByRefObject?

Hi,@Wally96333. The issue/exception is related to .NET Remoting, not WPF.

You could try to extend the lease time of your remote object by overriding the InitializeLifetimeService method in the object that derives from MarshalByRefObject.
